In A-deficient medium within a Rh1-driven experiment. For heat-shock driven expression, newly eclosed adult fly flies had been incubated at 37 for 45 min each day just before preparation. Within 0 days soon after eclosion, flies were frozen with liquid nitrogen and stored at -80 . The heads have been collected by sieving in liquid nitrogen, ground to powder and homogenized in buffer (50 mM Tris-Cl, 500 mM NaCl, pH 7.5) containing 1:200 Protein inhibitor cocktail VI (Calbiochem, San Diego, CA, UAS) utilizing BioMasher II (Wako Pure Chemical, Osaka, Japan) with motor drive. Debris was removed by centrifugation at 950 for 5 min and the membrane was precipitated by centrifugation at 21,500 for 15 min. About 30 l of membrane pellet were solubilized by 130 l of 1 CHAPS and placed on ice for 1 hr, and also the insoluble membrane was removed by centrifugation at 21,500 for 30 min. The extract was diluted fivefold by the buffer and 50 l of Anti-GFP-Magnetic beads (MBL, Nagoya, Japan) had been added and mixed by mild rotation for 18 hr. The magnetic beads were rinsed with 2100 l of 0.1 CHAPS in buffer as well as the bound protein was extracted by incubation in 20 l SDS-PAGE Sampling Buffer (BioRad) for five min at space temperature and an equal volume of Sampling Buffer with 2-mercaptoethanol was then added. The extracts were heat denatured for 5 min at 37 . SDS-PAGE and immunoblotting was performed as described above.Electron microscopyElectron microscopy was performed as described previously (Satoh et al., 1997). Samples had been observed on a JEM1200 or JEM1400 electron microscope (JEOL, Tokyo, Japan).Quantification of relative expression of mRNA of Rh1, TRP, and Arr2 normalized by Act5CWhole-eye mutant clones had been generated working with the FRT/GMR-hid technique (Stowers and Schwarz, 1999). Each eyes had been dissected from two adult flies per sample and cDNA was reverse-transcribed working with SuperPrep Cell Lysis and RT Kit for qPCR (Toyobo, Osaka, Japan) based on the manufacturer’s directions. Eyes with whole-eye clones of FRT40A have been made use of as a handle to acquire the relative regular curves. qPCR reactions were performed utilizing the StepOne real-time PCR method (Life Technologies) and KOD SYBR qPCR Mix (Toyobo, Osaka, Japan), according to the manufacturers’ guidelines. PCR condition was 98 for two min, followed by 40 cycles at 98 for 15 s, 55 for 15 s, and 68 for 45 s, along with a melt curve stage of 95 for 30 s, 60 for 1 min, and 0.three /s D-?Glucosamic acid medchemexpress increments to 98 ,Satoh et al. eLife 2015;4:e06306.

The relative expression levels had been normalized by Act5C.AcknowledgementsWe thank Drs U Tepass, C Montell, C Zuker, H Ryoo, and J Han who kindly provided fly stocks and reagents.
